| Abstract: | This Paper extends the basic idea of Wu anti-aliasing line algorithm to anti-aliasing for triangles with the combination of polygon scanning fill algorithm.An efficient algorithm to eliminate the aliasing at the vertexes of a triangle was proposed and the whole process of triangle drawing and anti-aliasing was realized as well.Finally the analysis of the algorithm's experimental results and its application were presented. |
